On solutions of $f(x)+f(a_1x)+...+f(a_Nx)=0$ and related equations [PDF]

open access: yesarXiv, 2011
We study some properties of the solutions of the functional equation $$f(x)+f(a_1x)+...+f(a_Nx)=0,$$ which was introduced in the literature by Mora, Cherruault and Ziadi in 1999, for the case $a_k=k+1$, $k=1,2,...,N$ and studied by Mora in 2008 and Mora and Sepulcre in 2009 and 2011.

Mora's holy grail: Algorithms for computing in localizations at prime ideals [PDF]

open access: yesInternat. J. Algebra Comput. 25(7) (2015), 1125-1143, 2015
This article discusses a computational treatment of the localization A_L of an affine coordinate ring A at a prime ideal L and its associated graded ring Gr_a(A_L) with the means of standard basis techniques. Building on Mora's work, we present alternative proofs on two of the central statements and expand on the applications mentioned by Mora ...

Linear least squares estimation of the first order moving average parameter [PDF]

open access: yes, 2002
We propose an iterative procedure to minimize the sum of squares function which avoids the nonlinear nature of estimating the first order moving average parameter and provides a closed form of the estimator.

The impact of new millennium crises on the power of Islamic banks in deposit markets

open access: yesInternational Journal of Finance &Economics, EarlyView.
Abstract We investigate the impact of three crises on the power of Islamic banks in deposit markets: the Global Financial Crisis, 2007–2009 (GFC), the Arab Spring political crisis, 2011–2013, and the COVID‐19 health crisis, 2020–2022. Applying difference‐in‐difference (DID) and GMM techniques to panel data for 2004–2022, we find that the power of ...

Restless bandit marginal productivity indices I: singleproject case and optimal control of a make-to-stock M/G/1 queue [PDF]

open access: yes, 2004
This paper develops a framework based on convex optimization and economic ideas to formulate and solve by an index policy the problem of optimal dynamic effort allocation to a generic discrete-state restless bandit (i.e. binary-action: work/rest) project,

A systematic review and meta‐analysis of parental mentalization in fathers and mothers

open access: yesInfant Mental Health Journal: Infancy and Early Childhood, EarlyView.
Abstract Despite the growing literature on parental mentalization (including measures such as mind‐mindedness, parental reflective functioning, and parental insightfulness), considerably less research on parental mentalization has been conducted with fathers than with mothers, leaving important gaps in our understanding of gender differences in the ...

Optimizing ddRAD sequencing for population genomic studies with ddgRADer

open access: yesMolecular Ecology Resources, EarlyView., 2023
Abstract Double‐digest Restriction‐site Associated DNA sequencing (ddRADseq) is widely used to generate genomic data for non‐model organisms in evolutionary and ecological studies. Along with affordable paired‐end sequencing, this method makes population genomic analyses more accessible.
